More specific settings overwrite others

UrlToMediaTag.convert(url, :width => '400px', :settings => {:image => {:width => '100%'}, :vimeo => {:show_title => true})
any   -> :width => '400px'
image -> :width => '100%'
vimeo -> :width => '400px', :show_title => true

Videos get default settings

:width => 640,
:height => 480,
:class => "url-to-media-tag-video",
:frameborder => 0

Find

urls = text.scan(%r{https?://[^\s]*})

Replace

text_with_embed = text.gsub(%r{https?://[^\s]*}){|url| UrlToMediaTag.convert(url) }

Alternative

• auto_html If you want more fancy stuff like auto-linking + strip-tags + active-record-integration (and more dependencies / C-extensions)

TODO

• let users choose which providers to convert
